HeartBeam, Inc.

Previous wording

We are a medical technology company focused on transforming cardiac care through the power of personalized insights. Our aim is to deliver innovative, higher resolution ambulatory cardiac monitoring solutions that can be used by patients anywhere to enable the detection and monitoring of cardiac disease outside of a healthcare facility. Our ability to develop higher resolution Electrocardiogram (“ECG”) solutions is achieved through the development of our proprietary and patented technology platform that allows us to collect the heart’s electrical activity from three distinct directions and synthesize a 12-Lead (“12L”) ECG from these signals. In recent studies, our approach has demonstrated diagnostic insights similar to a standard 12L ECG for arrhythmia assessment. The data from these studies was also submitted to the FDA as part of our recent FDA submission.

Previous wording

We believe our Products (“Products” or “Product”) and services will benefit many stakeholders, including patients, healthcare providers, and healthcare payors, and will also address the rapidly growing field of ambulatory cardiac health monitoring. As part of our long-term vision, we believe that we are uniquely positioned to play a central role in ambulatory cardiac monitoring including high-risk Coronary Artery Disease(“CAD”), given positive, proof-of-concept data from the initial feasibility studies that demonstrated comparable performance of the HeartBeam System and the standard 12L ECG in ischemia detection. CAD patients are at increased risk for a heart attack or Myocardial Infarction (“MI”). Additionally, our unique portable form-factor will make high-fidelity insights easily accessible, wherever patients are, compared to a standard 12L ECG which is typically limited to a healthcare setting. The initial product and service offering is expected to be an ambulatory device, carried by patients, which can synthesize a 12L ECG for manual assessment of arrhythmia by physicians.

Previous wording

The HeartBeam System (previously referred to as “AIMIGOTM”) was granted FDA clearance on December 13, 2024. The HeartBeam System is the first U.S. Food and Drug Administration (“FDA”) cleared cable-free, ambulatory ECG that captures the heart’s electrical signals from three distinct directions for high-fidelity data collection and advanced diagnostics for arrhythmia assessment. The HeartBeam System is comprised of a credit card sized 3-Lead ECG recording device, a patient application, a physician portal, and powerful cloud-based algorithms.

Previous wording

In January 2025, the Company filed a 510(k) application for the software algorithms that synthesize a 12L ECG from the 3-Lead ECG recorded signal obtained by the HeartBeam System. The software synthesizes these signals into a familiar 12L ECG display, using a personalized transformation matrix. This latest submission builds on HeartBeam’s recent FDA clearance, and once cleared by the FDA, the cumulative result will be an ambulatory device, carried by patients, which can synthesize a 12L ECG for manual assessment of arrhythmia by physicians.

The submission included results from the VALID-ECG Studyprospective multicenter pivotal trial, conducted to clinically validate of the HeartBeam 12L ECG synthesis software for arrhythmia assessment in comparison to a standard 12L ECG.

Previous wording

In April 2025, the Company announced that the VALID-ECG pivotal study successfully met its clinical endpoints. The study evaluated the mean difference in ECG intervals and amplitudes between HeartBeam’s synthesized 12L ECG and a simultaneously collected standard 12L ECG. Intervals and amplitudes are important in assessing non-life-threatening arrhythmias. Data showed a 93.4% overall diagnostic agreement, indicating that HeartBeam’s synthesized 12-lead ECG can support diagnosis of arrhythmias in a manner consistent with standard 12L ECGs. The VALID-ECG pivotal study was a multicenter trial that enrolled 198 patients across five clinical sites in the US, including Allegheny Health Network, Atlanta Heart Specialists, Mount Sinai Hospital, Northwell Health and Piedmont Heart Institute. Efforts were made to enroll patients with a diverse demographic profile reflective of the intended use population in the United States.
